Gas tank has just been cleaned,from old varnished,under a dollar a gallon gas.Got a new sending unit,before I hook it all up,how do I check the line to the fuel pump(engine is a 250 6cyl 70's Olds)for gunk?If I need to use compressed air is it sufficient?Can the lines be taken off and cleaned or dipped in a "hot tank"?I have a 53 3600 I'm using for parts,hard lines included,with slightly rusted innards.Thanks again as always.I learn something new & fun on this site everyday!
